Hi Gang,
I built a small diesel engine that has a 3mm pressed-in crankpin. Didn't get the fit right and it came loose. No big deal - just make another hole in crankweb and try again. How much smaller should that hole be than the actual pin size? For folk who think in inches, think about fit for a .125 inch pin. Pin is a cut down needle roller, going into steel cranbkweb.
